About this app

This is an app that uses a smartphone to receive signals from the Indoor Signal Device Link System, a welfare device that allows people with hearing impairments to detect sounds in their daily lives (visitors, incoming calls, the sound of fire alarms, etc.) using lights and vibrations, and notifies them.

We help people with hearing loss to live without missing out on important information.
